Sant Cugat, Barcelona, España Lupa AI Software A tiempo completo

Abaout Lupa A.I:

Lupa AI is a fast-growing technology company focused on building AI-powered tools for image enhancement and upscaling. Our platform is already live, trusted by more than 10,000 active subscribers, and used daily by creators and professionals who rely on high-quality visual output.

We are currently at a key stage of expansion. After validating the product and market, our focus is now on strengthening the technical foundations of the company and preparing the platform to scale to the next level. This is a moment where long-term technical decisions really matter, and we are looking for people who want to be part of that journey.

The Project:

So far, we have moved fast and built efficiently using no-code solutions to get the product to market. Now, our goal is to take a major step forward and build a new web platform from scratch, based on clean, well-structured, and scalable code.

This is not about experimentation or short-term delivery. It is about creating a solid technical base that will support the growth of the product, the team, and the business over the coming years.

The Role:

We are looking for a Senior Full-Stack Developer with strong, hands-on experience across both front-end and back-end development.

You will play a key role in designing and building the new code-based web platform, working closely with the team to make architectural decisions, improve performance, and ensure long-term maintainability. This is a role with real ownership, where your technical choices will directly impact the future of the product.

We are specifically looking for someone with extensive experience as a Full-Stack Developer, who feels comfortable taking responsibility, understanding existing systems, and building robust solutions from the ground up.

This is a
full-time, on-site position
based in
Sant Cugat del Vallès (Barcelona)
.

What we're looking for:

  • Strong professional experience as a Full-Stack Developer.
  • Solid knowledge of modern front-end development and web standards (HTML, CSS, JavaScript, modern frameworks).
  • Proven experience in back-end development and working with databases and APIs.
  • Ability to design clean, scalable, and maintainable architectures.
  • Product-oriented mindset and strong problem-solving skills.
  • Ability to work autonomously while collaborating closely with a small, fast-moving team.
  • Full availability and genuine interest in a
    long-term role
    , not a short-term project.

Why join Lupa A.I:

You'll be joining the company at a defining moment, with an existing product, a growing subscriber base, and ambitious plans to scale significantly. You'll have the opportunity to build core systems from the ground up, influence technical direction, and grow alongside the company as we take Lupa AI to the next level.

If you're looking for ownership, impact, and the chance to build something meaningful over the long term, we'd love to hear from you.
